Patent DE-2834677-A1 (DE)
Title: Splash proof housing for electrical controls - has screened circular air inlets in vertical walls to allow flow of cooling air
Inventor: BUCHER HEINZ
IPC: H01F27/02
Filed: 1978-08-08
Abstract: The vertical sides of the electrical housing equipment are provided with screened vents to allow cooling air flow circulation and prevent ingress of water spray. On the inside, each vent hole is shielded by a plate (63) fixed at a small distance from the wall by a solid, channel shaped support (64). This support is open at the top to give a slit (65) through which air can enter or leave the inside of the housing. The vents are normally placed near the top and bottom of the vertical walls to assist in natural air circulation. The housing can be used for control equipment for air pumps used to agitate water in special baths.

Title: Hydraulic power generating installation - has shaft lifting water hydraulically to increase head available to drive turbines
Inventor: SCHROETER DIETER
IPC: F04B17/00
Filed: 1979-03-13
Abstract: A weir (1) is constructed at the side of a flowing river. A vertical shaft (2) joins a horizontal shaft (3) through the base of the weir.

Title: Moulding sand degeneration shaker tray - with anchor braces shaped for optimum unbalances force absorption
IPC: B22C5/04
Filed: 1979-04-12
Abstract: Shaking trough, driven by an unbalance motor, for the regeneration of spent moulding sand with a synthetic resin binder in foundries, has in the bottom of each tray a layer of hydraulically setting casting cpd. surmounted by a thick layer of high-alumina corundum.

It is built up of two identical flat panels of strong elastic material (e.g. GRP), so shaped that when joined in a watertight manner - by gluing, welding, rivetting or the like - along all but their longest edges, the joined edges form a bow, keel and stern. The boat shape is achieved by inserting easily removable spacers held by snap-closures between the edges left free. The open top can have a tarpaulin cover, possibly with a single opening or several openings with rapid-closure equipment.
Patent DE-2934238-A1 (DE)
Title: Lightning arrester spark gap - with spacing disc between electrodes releasing arc quenching hydrogen when heated
Inventor: HASSE PETER DR ING
IPC: H01T4/10
Filed: 1979-08-24
Abstract: Parent Patent described a spark gap for use as surge arrester in low-voltage installations and for the lightning protection of electrically sepd. circuits, with two electrodes separated by an insulating layer. Improvement is that the insulating layer is of a material which, when heated by an arc, releases gas. This gas displaces the arc outwards, cools and thus quenches it so that the mains current is interrupted. Arrangement requires only one spark gap to interrupt the subsequent mains current after a stroke of lightning for 220V 50 Hz systems, and fewer spark gaps for higher voltages.

Title: Turn indicator reflector and lens for car light - employs slotted mirror behind lamp glass to stop amber light showing when bulb is not lit
Inventor: HAAS GUNTHER
IPC: F21V9/08
Filed: 1979-10-19
Abstract: The lamp arrangement assists in eliminating driving errors by having no amber colour showing at the turn indicators unless the appropriate lamp is lit. The lamo filament (12) is at the focal point of a parabolic reflector (10). Filter screens (15,21,22,23) provide the amber light when the lamo (24) is lit. In front of the reflector ooening, and inside the lens cover (19), is a series of strio elements (16) with mirror surfaces on each side. These elements are angled at 45 degrees to the reflector axis, and hence to the direction of the reflected light beams (25). With the lamp lit, amber light is emitted from the assembly by reflection through the mirrors. With the lamp off the assembly appears, from the outside, as an untinted lamp.
